Cocos2d-x 3.4 进度条

旋转进度条

auto s = Director::getInstance()->getWinSize();

auto to1 = Sequence::createWithTwoActions(ProgressTo::create(2,100),ProgressTo::create(0,0));//旋转进度条

auto left = ProgressTimer::create(Sprite::create("Images/grossini.png"));

left->setType(ProgressTimer::Type::RADIAL);

left->setReverseProgress(true);//反转执行

addChild(left);

left->setPosition(100,s.height/2);

left->runAction(RepeatForever::create(to1));

水平进度条

auto to2 =

auto left = Type::BAR);//BAR 水平进度条

left->setMidpoint(Vec2(1,0));//从右到左 ，Vec2(0,0)为从左到右

left->setBarChangeRate(

addChild(left);

left->setPosition(100,175); font-family:新宋体; font-size:9.5pt">RepeatForever::create(to2));

垂直进度条

auto t3 = Type::BAR);

left->setMidpoint(Vec2(0,1));//从上到下，Vec2(0,0)为从下到上

left->setBarChangeRate(

addChild(left);

left->setPosition(100,175); font-family:新宋体; font-size:9.5pt">RepeatForever::create(t3));

auto t5 = Vec2(0.5f,0.5f));

left->setBarChangeRate(//从中心向四周扩散，Vec2(1,0)从中心向两边扩散，Vec2(0,1)从中心向山下扩散

addChild(left);

left->setPosition(s.width/2,175); font-family:新宋体; font-size:9.5pt">RepeatForever::create(t5));

可变换旋转中心的旋转进度条

auto t4 = Type::RADIAL);

left->setMidpoint(Vec2(0.75f,0.25f));//设置旋转中心点

left->setBarChangeRate(RepeatForever::create(t4));

进度条搭配其他动作

auto t6 = ProgressTo::create(6,0));

auto hint = Sequence::create(TintTo::create(1,255,0),255),nullptr);

auto left =

left->runAction(RepeatForever::create(t6->clone()));

left->runAction(RepeatForever::create(hint->clone()));

使用缓存中图片加载进度条，通过加载plist文件

auto t7 =

SpriteFrameCache::getInstance()->addSpriteFramesWithFile("zwoptex/grossini.plist");

auto left = Sprite::createWithSpriteFrameName("grossini_dance_01.png"));

left->setMidpoint(

left->setBarChangeRate(

addChild(left);

left->setPosition(300,300);

left->runAction(RepeatForever::create(t7->clone()));
